Problem 6: SpaceX rocket. You have to design the supports that hold the SpaceX rocket prior to launch (it obviously can't rest on the nozzles - the weight would mess them up, and any floor under them would keep the fuel from flowing through correctly at the start and make the initial combustion back up into... the fuel tanks...) How heavy is a Falcon 9 rocket? Per Wikipedia, it has a diameter of 3.7m and is 70m tall Assume it's filled with liquid oxygen and kerosene, which are both about... the density of water а. b. Look up the actual mass on Wikipedia... how much of the rocket is empty space around the fuel tanks, etc.? I'd guess 20-25%. Am I right?
